Configuration

5.1. Access to the APS Command Mode

When the APS Command Mode is active, commands can be invoked to select parameters, and

connect or disconnect ports.

Note:

Command Mode

cannot

be accessed from a Buffer Mode Port, Passive Mode

Port, or any port that is currently connected to another APS port.

1. Start your communications program (e.g. ProComm

®

). Make certain the APS and

ProComm are set for the same parameters (e.g. baud rate, parity, etc.).

2. Access the Command Mode.

a)

Local Access:

To access the command mode from a local PC that is connected to the

APS via cable, press

[Enter]

.

i.

There must be no other characters preceding

[Enter]

. If you have already hit

other keys, press

[Enter]

twice.

ii. If the Supervisor Password has been defined, the password prompt will be

displayed. Key in your Supervisor or Port password and press

[Enter]

. The

"APS>" prompt will appear.

b)

Modem Access:

To access the command mode via modem, proceed as follows:

i.

Dial the number for the external modem connected to the APS.

ii. If you have defined the Supervisor Password, a prompt will be displayed. Key in

your Supervisor or Port password and press

[Enter]

. If the Supervisor Password

has

not

been defined, just press

[Enter]

. The "APS>" prompt will appear.

5.2. System SetUp Ports

As discussed previously in Section 3 of this User’s Guide, Ports 1 and 2 are designated as

System SetUp Ports. Ports 1 and 2 will always permit password protected access to Supervisor

Level command functions, even when the unit is initialized to default parameters.
In order to ensure that access to command functions is always available, Ports 1 and 2

cannot

be configured as Buffer Mode or Passive Mode Ports (Buffer and Passive Mode Ports are not

able to access the Command Mode.) In addition, Ports 1 and 2 always permit password

protected access to Supervisor Level commands; the Supervisor Mode

cannot

be disabled at

these two ports.

5.3. Password Functions

The APS features two different types of passwords; the Supervisor Password and the Port

(User) Passwords. The Supervisor Password allows system administrators to invoke unit

configuration commands, and the Port Passwords allow users to access specific ports in order

to create connections between permitted ports or view port configuration parameters.
